Silicon carbide brick material

Q: what is best for making refractory insulation for Blast furnace, hot stove.: clay brick, insulating brick can endure relatively high temperature and last longer than the general fireproof fiber.

Q: which kind of fire?bulkhead is better?: Fire bulkhead also known as non-combustible fire retardance board, and it's made by various incombustible?material after the scientific pressing, and has good flame resisting properties, it's non-combustible time can reach over 3 hours, high mechanical strength,it has characteristics of non-explosive, water and oil resistance, good chemical corrosion resistance and non-toxic. As for the combustion test of YD-Ba-type inorganic fire?bulkhead, it's best to be deformation under the flame temperature of 1000 ℃, the indicators comply requirements of GA161-1997, combustion performance reaches A level standards of GB8624(non-flammable). J fire bulkhead is mainly applicable to the fireproofing protection and fireproofing isolation of cables with all kinds of voltage?classes laid on scaffold or bridge. It's widely used in cable project fireproofing and fire?retardant in the places with crowded cables, such as various power plants, chemical companys, iron and steel smelting enterprises, mines,etc. It's also the best fireproofing and fire?retardant materials of fireproofing and fire?retardant projects in indoor decoration of public places, such as large shopping malls, hotels, guesthouses, sports hall, closed clothing market, light industrial markets, theaters and so on. Construction method: Fire?bulkhead products can be cut by saw, according to the shape required to be made in the construction site, using steel brackets or expaned anchor bolt to fix it while assembling, steel brackets should be coated with fire-resistant coating for steel structure. You can also use various cable and fireproofing trays made of fire bulkhead, and used in the board gaps.

Q: Physical and chemical indicators of various refractory.: please read"Refractories Standard Series" for refernece, general business standards are higher than the national standard.

Q: What's the requirements of fire-fighting criteria of heat insulating material?: It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.

Q: How to do environmental impact assessment for refractory Co., Ltd.: 1, first of all, the EIA unit and the construction party signed the EIA contract. The contract is only legally valid. Generally speaking, the contract will indicate that the first payment has been received before the work begins.2. Collecting information. This is a very important link in the EIA, which is directly related to the quality of the eia. There is a great variety of data,Generally, the construction party will write a list of environmental impact assessment information.

Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?: Graphite, Magnesium Oxide, and alumina are all feasible.

Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?: You mean furnace lining or ladle lining? Generally magnesia is used as furnace lining, but heat preservation should be practiced when shut down, or brasque would crack. Surly you can employ existing furnace lining which is sold in Tianjin, a little bit expensive, the average lining could be used for 300 furnaces. The furnaces made by magnesia myself break down after 40 furnace were finished. What I referred is a furnace weighing 2 tons, as for a bigger furnace, the existing brasque would be OK. What is the difference between furnace lining and ladle lining? Can you give me more detail about the materials of making a furnace weighing 2 ton? Why others can burn 80-90 furnace with 0.7-ton furnace; over 200 furnaces with 2 ton? What are these ingredients? What I know is just magnesia, magnesium borate, and together with boric acid, they also have many types, which one should I use? Thank you!

Q: Where is the sizing nozzle for refractories? Just enter the line, master into!: Hua Heng refractories in the industry reputation is good, especially in the Southern small steel sales are among the best!

Q: What is the material of fire resistant glass reinforced plastics grating?: What is the material of fire resistant glass reinforced plastics grating?

Q: What kind of foundry ingot refractory materials are there? Please be more detailed.: This question is a little bit extensive, because there are too much foundry ingot refractory materials.
